What should a driver/operator do if the slack adjuster is "out of adjustment"?

If the slack adjuster is "out of adjustment," the critical action a driver/operator should take is to chock the wheels and apply the brake. This is essential for safety reasons. An "out of adjustment" slack adjuster means that the braking system may not be functioning correctly, which can lead to reduced braking performance and an increased risk of accidents.

Chocking the wheels ensures that the vehicle stays stationary and prevents any unintended movement while the driver addresses the issue. Applying the brake reinforces the safety measure by further stabilizing the vehicle, particularly if it is on an incline or if the situation requires immediate attention. It allows the driver to evaluate and rectify the problem without risking an unintentional rollaway.

Adjusting or replacing the slack adjuster immediately might not be safe if there is a risk of movement. Continuing to drive until the next service is inadvisable because it could compromise safety due to ineffective braking, increasing the risk of an incident. Thus, chocking the wheels and applying the brake is the most prudent and safe choice in this situation.
